That's what countries spend in total, I was talking about in context of individuals with good jobs (employer provided healthcare)

Btw a large reason why the US spends more on healthcare than other countries is research & development.

Don't you lose your job sponsored health care after being laid off ? Or is it expected that companies keeps you employed when you get a cancer / other high impact health issues ?

You'll most likely fall under COBRA protection (https://www.healthcare.gov/unemployed/cobra-coverage/)

where you can keep your employer coverage for 18 months while you find a new job.
